A 235kW solar energy system is installed on the roof of Medford’s Department of Public Works building
The City of Medford has committed to the goal of becoming carbon neutral by 2050. This means that our infrastructure must rely on other low-emission energy systems. Solar energy will play an important role in meeting this target, and Medford has already started to invest in solar systems for our public buildings. These systems additionally benefit the City by providing electricity at a lower rate, creating savings on our energy bills.

Department of Public Works
In 2019, the City worked with Solect Energy and PowerOptions to install a 235-kilowatt photovoltaic solar array on the roof of the new DPW building. The array generates approximately 100% of the building’s energy usage and serves to reduce the City’s electrical expenses by a projected $11,000 annually. The array is a power purchase agreement, meaning that Solect Energy financed, installed, and will service the roof-top solar array, while the DPW receives the power generated at a fixed price for a period of 20 years.
In summer 2021, the City is also working to install a 100-kilowatt / 225-kilowatt-hour solar battery storage system and a fully functional micro-grid. This addition will allow the DPW building to remain online in the case of power outages and provide continuous service in the event of an emergency.
The new Medford Police Station opened in December 2020. On its roof is a 60-kilowatt solar system, fully owned by the city, which helps power the station. The building itself is highly energy-efficient and uses half the energy that it would consume if it was built to only meet the current energy code. The station uses zero fossil fuels for its heating, cooling, and ventilation systems, and instead, relies on heat pumps and a highly efficient energy recovery ventilation system.

The new Medford Public Library Building is planned to open in Fall 2021. The Library has purchased 126kWh of solar for the new building which will be used to power the facilities. The building is all-electric and with its on-site solar power, the Medford Public Library is the first net-zero public library in Massachusetts. Its energy-efficient and net-zero design is expected to qualify for LEED silver certification once construction is complete.
